[0042] As Figures 1 to 17 ​​​​As shown, the small household photovoltaic power generation and energy storage integrated device of the present application comprises a photovoltaic panel 1, a box 2, a shielding device 3, an adjusting assembly 4, a first traction rope 5 and a second traction rope 6. The photovoltaic panel 1 is arranged inside the box 2 for storage and protection of the photovoltaic panel 1, and the shielding device 3 is used for shielding the box 2 with the upper end opening, protecting the surface of the photovoltaic panel 1, and lifting the photovoltaic panel 1 so that the photovoltaic panel 1 is lifted from the inside of the box 2 to the outside to receive light. The adjusting assembly 4 is used to cooperate with the first traction rope 5 and the second traction rope 6 to change the length of the second traction rope 6, control the distance between one side of the photovoltaic panel 1 and the adjusting assembly 4, and thus make one side of the photovoltaic panel 1 in an inclined state, so as to receive light at the best angle in different seasons and improve the power generation efficiency.

[0043] The photovoltaic panel 1 is provided with third guide wheels 7 at both ends, and the bottom of the photovoltaic panel 1 is provided with a connecting shaft 8, and the third guide wheels 7 are arranged at both ends of the connecting shaft 8, and the third guide wheels 7 at both ends can rotate on the connecting shaft 8 independently. Of course, the photovoltaic panel 1 can be arranged on a mounting frame, and then connected with the connecting shaft 8 through the mounting frame.

[0044] The box 2 is used for storing the photovoltaic panel 1, and the box 2 is open at the upper end and forms a receiving chamber 9 in the middle, and the receiving chamber 9 has a storage battery 10, and the storage battery 10 is located at the lower end of the photovoltaic panel 1. Heat dissipation holes can be formed in the bottom of the box 2 to facilitate heat dissipation of the storage battery 10 and discharge of rainwater.

[0045] The shielding device 3 is arranged on the box 2, and the shielding device 3 comprises a motor 11, symmetrical sunshields 12 and guide pieces 13. The guide pieces 13 are arranged at the four corners of the box 2, the photovoltaic panel 1 is mounted on the box 2 and forms a sliding connection with the guide pieces 13. The guide pieces 13 are provided with sliding grooves 14, and the sunshields 12 can be directly mounted in the sliding grooves 14 or arranged in the sliding grooves 14 through rollers, so that the sunshields 12 can slide in the sliding grooves 14 after being driven by the belts 15, and the two sunshields 12 can move away from each other to lift the photovoltaic panel 1.

[0046] Meanwhile, one end of the sunshield 12 is provided with a connecting piece 16, the connecting piece 16 is provided with a connecting port 17, the middle of the guide piece 13 has a driving wheel, the driving wheel is sleeved with the belt 15, the motor 11 is connected with one of the driving wheels, and the connecting piece 16 is connected with the belt 15 through the connecting port 17. The first traction rope 5 and the second traction rope 6 are also connected with the connecting piece 16, the two ends of the first traction rope 5 and the second traction rope 6 are fixed, so that when the sunshields 12 move, the first traction rope 5 and the second traction rope 6 can be pulled, and the third guide wheels 7 are driven upward through the traction ropes, thereby lifting the photovoltaic panel 1.

[0047] When the user does not need to use the motor 11 to drive or does not need the motor 11 to position the sunshades 12, a sliding piece 18 is arranged on one side of the guide piece 13, the sliding piece 18 is arranged on the guide piece 13 through a sliding sleeve 19, the sliding piece 18 is provided with a push plate 20, and the sunshades 12 are provided with limiting grooves 21 matched with the sliding piece 18. After the symmetrically arranged sunshades 12 are unfolded, the sliding piece 18 can be pushed to slide in the sliding sleeve 19, so that one end of the sliding piece 18 is arranged in the limiting groove 21, thereby positioning the unfolded sunshades 12 and keeping the sunshades 12 consistent with one end of the guide piece 13, reducing the force influence of the photovoltaic panel 1 itself gravity pulling the traction rope on the motor 11, and protecting the motor 11.

[0048] The first traction rope 5 and the second traction rope 6 are used to pull the photovoltaic panel 1, the middle of the first traction rope 5 is in contact with the first guide wheel 22, the middle of the second traction rope 6 is in contact with the adjusting assembly 4, and the two ends of the first traction rope 5 and the second traction rope 6 are respectively connected with the symmetrically arranged sunshades 12. The first traction rope 5, the second traction rope 6 and the third guide wheel 7 are in contact. The box body 2 is also provided with a fourth guide wheel 51 for keeping the first traction rope 5 and the second traction rope 6 in a horizontal state.

[0049] The first guide wheel 22 and the second guide wheel 23 are provided with symmetrically arranged fixing pieces 24, the first traction rope 5 is located between the fixing piece 24 and the first guide wheel 22, the second traction rope 6 is located between the fixing piece 24 and the second guide wheel 23, and the fixing piece 24 is installed on the first guide wheel 22 and / or the second guide wheel 23 through a pin shaft 25. So that the first traction rope 5 does not deviate from the first guide wheel 22, and the second traction rope 6 does not deviate from the second guide wheel 23. At the same time, the second guide wheel 23 drives the second traction rope 6 to rotate, and the second traction rope 6 is stored, so that the second traction rope 6 is wound on the second guide wheel 23, thereby changing the distance between the second guide wheel 23 and the photovoltaic panel 1.

[0050] In order to better adjust the angle of the photovoltaic panel 1, the prior art generally uses the motor 11 to adjust, which can be more convenient, but for household use, consumers pay more attention to cost, and the use of the motor 11 undoubtedly increases the cost, making the overall selling price higher. And there is a certain interval in the time of angle adjustment, and the motor 11 is wasted when it is not needed to be adjusted frequently, and the motor 11 is easily damaged in outdoor use for a long time. The present application adopts the traction rope mode, cooperates with the rotation of the adjusting assembly 4, so that the second traction rope 6 can be freely changed in length, which is convenient for angle adjustment of the photovoltaic panel 1, has compact structure design, is convenient to adjust, has long service life and reduces cost.

[0051] The adjusting assembly 4 is used for changing the inclination angle of the photovoltaic panel 1, and is arranged at one side of the box 2 and between the symmetrically arranged sunshields 12. The box 2 is further provided with a first guide wheel 22 which is arranged opposite to the adjusting assembly 4.

[0052] The adjusting assembly 4 is composed of a second guide wheel 23, a limiting disc 26, a mounting disc 27, a driving disc 28 and a driving member 29. One end of the driving disc 28 is connected with the second guide wheel 23 through the limiting disc 26, and the other end is connected with the driving member 29. The limiting disc 26 is provided with a positioning tooth 30 in the middle thereof. The positioning tooth 30 is a one-way tooth, and is in an inclined state so as to facilitate the limiting tooth 31 to rotate in the forward direction and the reverse direction.

[0053] The driving disc 28 is provided with the limiting tooth 31 which cooperates with the positioning tooth 30. The mounting disc 27 is sleeved on the driving disc 28 and the limiting disc 26. The driving member 29 can drive the driving disc 28 to rotate in the forward direction and the reverse direction in the limiting disc 26, so as to change the length of the second traction rope 6 and shorten the distance between the third guide wheel 7 and the adjusting assembly 4.

[0054] The limiting disc 26 is composed of a fixed body 32 and a ring body 33. The ring body 33 is arranged on the fixed body 32. The fixed body 32 is mounted on the outer wall of the box 2. The ring body 33 is arranged in the middle of the driving member 29. The positioning tooth 30 is arranged on the inner wall of the ring body 33. The limiting disc 26 is provided with a mounting hole 34 in the middle thereof. An installation end 35 is arranged in the receiving chamber 9 through the mounting hole 34.

[0055] The driving member 29 is composed of the installation end 35, a connecting end 36 and a disc body 37. The installation end 35 is connected with the second guide wheel 23 through the limiting disc 26. The connecting end 36 is connected with the driving member 29. The disc body 37 is provided with uniformly arranged pushing portions 38. The pushing portions 38 are provided with elastic arms 39. The elastic arms 39 are provided with contact portions 40. The limiting tooth 31 is arranged on the contact portions 40. The pushing portions 38 and the elastic arms 39 form a placing area 41. The driving member 29 is provided with a driving portion 42 in the middle thereof. The driving portion 42 is arranged in the placing area 41. The elastic arms 39 and the contact portions 40 are provided with a guide inclined surface 43. The guide inclined surface 43 and the limiting tooth 31 form a blocking portion 44.

[0056] Meanwhile, there is a deformation area 45 between the elastic arm 39 and the disc body 37, and the elastic arm 39 is shrunk into the deformation area 45 after being forced. The pushing part 38 has an a surface in contact with the driving part 42, and the guide inclined surface 43 is adjacent to the other surface of the driving part 42. When the driving member 29 is rotated forward, the driving part 42 drives the a surface of the pushing part 38 to rotate, so that the elastic arm 39 is forced to be compressed under the pushing of the positioning tooth 30. When reverse rotation is needed, the position of the driving part 42 is relatively inconvenient, but the elastic arm 39 can be compressed through the guidance of the guide inclined surface 43, so that the elastic arm 39 moves to the deformation area 45, thereby making the limiting tooth 31 disengage from the positioning tooth 30, and the blocking part 44 can block the driving part 42, so that the reverse rotation of the driving member 29 can be realized, and the second traction rope 6 wound on the second guide wheel 23 can be released.

[0057] The connecting end 36 is provided with a buckle 46, the driving member 29 is composed of an outer cover 47, a driving arm 48 and a hand wheel 49, the inner part of the outer cover 47 is provided with the driving part 42, and the front end of the driving part 42 is arranged in the placing area 41 and in contact with the driving disc 28. The outer cover 47 is connected with the hand wheel 49 through the driving arm 48, and the middle part of the driving arm 48 has a clamping groove 50 matched with the buckle 46, so that the driving member 29 can drive the driving disc 28 to rotate.

[0058] As shown in Figure 17 After the second traction rope 6 is wound, the length is changed, and the first traction rope 5 is not wound and keeps the original length, so that one side of the photovoltaic panel 1 is higher and the other side is lower, thereby making the photovoltaic panel 1 better receive light and facilitating the adjustment of the angle of the photovoltaic panel 1.

[0059] The above only describes the preferred embodiments of the present application and should not be used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
